a lock nut 36. A ratchet wheel 37 is keyed to the knife spindle 18 beside the other arm 19 of the carrier and is engaged by a pawl 38. Such pawl is pivoted to swing freely on a stud 39 which projects from the adjacent side plate or support 40 of the machine frame. These parts are suitably dimensioned and positioned to locate the pawl in the space between the carrier arm 19 and the nearest disk knife, clear of either, and with the pawl extending in approximate coincidence with the path traversed by the under side of the ratchet wheel as the knives are advanced and retracted. A leaf spring 41 is made fast at one end to the pawl 38 and is free at the other end, bearing on an adjacent part of the swing frame with exertion of force tending to hold the pawl against the ratchet wheel yield ingly. The cooperating teeth of the ratchet wheel and pawl are complementally so inclined as to effect positive engagement as the knife is carried equiangularly around a common central axis.

These channels are open from end to end of the magazine and are of suitable shape and dimensions to contain each a row of axially alined cops. The magazine is mounted to rotate about the .above named axis on an axle rod 43 which projects parallel with the spindle axis from a bracket 44 suitably secured to the machine base as, for instance, by being pinned or clamped to a shaft 45 which protrudes from the base. All of the receiving compartments or passages referred to are equidistant from the pivot axis, and the pivot shaft is spacedto one side of the spindle axis a distance equal to that between the axis of the magazine and the axis or longitudinal median line of any compartment. Therefore, by turning the magazine about its axis any one of the receiving compartments may be located in alinement with the winding spindle. It should be noted that the outer end of the spindle and the adjacent end of the carrier are close together; that is, the distance between them is less than the length of the standard cop, whereby cops displaced by the pusher 15 enter the compartment which is at that moment alined with the spindle.

For turning the magazine there is a pawl and ratchet mechanism consisting of abutments or teeth 46 protruding from one end of the carrier and a pawl 47. The abutments are made as pins set into the magazine equidistant from the axis thereof and equiangularly arranged about the axis, in a number equal to the number of compartments.

The pawl is pivoted to a carrier arm 48 which swings about the shaft 45 and is connected with a lug 49. The latter is actuated by a roll or stud 50 on an arm 51 carried by a rock shaft 52 which is journaled in a bracket 53. A second arm 54 fixed to said rock shaft carries a roll or stud Said cam has a rising portion 56a, a descending portion 56b, and intermediate high and low dwells.

This last cam is associated with the cam 27, and with other cams controlling actions of other parts of the machine, and its features are so timed as to cause one of the compartments of the magazine to stand stationary in line with the spindle while a series of cops are being displaced from the spindle by the pusher l5, and to bring another compartment into receiving position during the winding phase of the cycle of the machine.

In the opposite end of the magazine from the ratchet abutments are notches 57, equal in number and similar in spacing to said abutments; and a pin 58 is contained in a socket in a sleeve 59 secured to the axle rod 43. A spring 60 presses this pin toward the magazine. The pin and notches have inclined engaging faces and are so located that when any one of the receiving compartments is correctly alined with the winding spindle, the pin projects into one of the notches and holds it there; while it is displaceable by the cam action of such contact faces when the magazine is turned by the pawl.

This magazine provides storage capacity for a large number of cops in a small space. It may be made long enough in axial direction to receive the cops from two or more winding operations in each compartment; in which case it need not be emptied until it has made a corresponding number of revolutions. That is, after having made one revolution and received cops in all its compartments, the next revolution results in more cops being added to those already in the compartments.

t will be understood from the foregoing description, and by reference to the prior patent on which the present disclosure is based, that the operations of the knives and magazine are timed in proper correlation with the other phases of the cycle of the complete machine. It will further bev apparent that these new features may be combined with other winding machines than the one disclosed in said patent; machines which may be more or less different from that one.

What I claim and desire to secure by Letters Patent is:

1. The combination with means for supporting and rotating an article to be cut into lengths, of a disk knife and means for bringing different arcs of the knife edge into contact with such article comprising the combination with means for moving the disk knife toward and away from the article, of a ratchet connected with the knife and a pawl mounted on a relatively stationary part of the machine in position to engage said ratchet wheel and rotate the same during the displacement of the knife in one direction.

2. In a cutting mechanism, the combination of a disk knife, a carrier on which said knife is rotatably mounted, means for moving said carrier back and forth, a ratchet wheel connected with the disk knife, and a relatively stationary pawl arranged to impart rotation to the ratchet with movement of the knife carrier in one direction only.

3. In a cutting apparatus, an oscillative knife carrier, a disk knife rotatably mounted on said carrier, a ratchet wheel connected with said disk knife, and a pawl cooperatively associated with said ratchetto impart rotation thereto when the carrier is moved in one direction and to permit passage of the ratchet without rotation when the carrier is moved in the opposite direction.

4. In a cutting apparatus, the combination with means for supporting and rotating the article to be cut, of a disk knife, means for advancing the knife into cutting position and retracting it therefrom, means for restraining the knife from rotation while cutting the tube, and

means for rotating the knife to present difi'erent portions of its edge to the tube.

5. In a tube severing machine, the combination with means for supporting and rotating 2. tube, of a disk knife, means for advancing the knife into cutting position and retracting it therefrom, means for restraining the knife from rotation while cutting the tube, and means organized to operate during times while the knife is out of cutting position to turn the knife so that a different part of its edge is presented for a subsequent cutting action.

6. In a cutting, apparatus, the combination with means for supporting and rotating an article to be cut into lengths, of a gang of disk knives arranged side by side for cutting the article, a knife carrier, a shaft rotatably mounted on said carrier on which said knives are secured, a ratchet wheel secured to said shaft, means for moving the carrier back and forth in a path which brings the knives into contact with the article and withdraws them therefrom, and a pawl connected to a stationary part of the machine in position to cooperate with the ratchet wheel for turning the ratchet wheel during the translative movement of the carrier in one direction.

'7. The combination withmeans for supporting and propelling an article to be cut into lengths, of a disk knife, means for supporting said knife in position to cut the article, means for normally preventing rotation of the knife while in cutting action upon the article, a ratchet and pawl mechanism in rotation impartingrelationship to the knife, and means for actuating said pawl and ratchet mechanism from time to time to turn the knife sufficiently to bring different arcs of its edge into engagement with the article.
